Hopkins' Rose
Okenia rosaceaAlso known as Hopkins' Rose Nudibranch, Rosy Nudibranch, Pink Hopkins' Rose
Hopkins' Rose nudibranchs resemble vibrant pink, shaggy pom-poms scattered across rocky Pacific tide pools. These striking sea slugs derive their brilliant coloration directly from the pink encrusting bryozoans they consume. During warm-water ocean events, they can experience dramatic population blooms, carpeting the intertidal zone in bright rose hues.

- Safe to observe at a normal distance.
Responsible observation
- Look in tide pools: Search shallow, rocky intertidal pools during low tide, especially where pink bryozoan crusts are visible.
- Do not touch: Their delicate, long papillae are easily damaged by handling.
- Watch for blooms: Look for them during warm-water events when populations can dramatically spike.
